causes such a drug or substance to be taken by a protected animal,
and the person knows the drug or substance to be poisonous or injurious.
A person (“person A”) who is responsible for an animal commits an offence if—
without lawful authority or reasonable excuse, another person—
administers a poisonous or injurious drug or substance to the animal, or
causes such a drug or substance to be taken by the animal, and
person A—
permits that to happen, or
knowing the drug or substance to be poisonous or injurious, fails to take such steps (whether by way of supervising the other person or otherwise) as are reasonable in the circumstances to prevent that happening.
In this section, references to a poisonous or injurious drug or substance include a drug or substance which, by virtue of the quantity or manner in which it is administered or taken, has the effect of a poisonous or injurious drug or substance.
